# NBIA Summer School on Computational Astrophysics

19-23 August 2013
Europe/Copenhagen timezone

# Virtual Machine Image

To run the virtual machine, you will need VirtualBox. Get it at https://www.virtualbox.org/wiki/Downloads

A link to download the virtual machine image will be placed here. The files will also be available on USB memory sticks.

The Virtual Machine files are available at:
VBox file:  http://www.nbi.dk/~gmurphy/NBIA%20Summer%20School%202013.vbox
Machine image (8GB): http://www.nbi.dk/~gmurphy/NBIA%20Summer%20School%202013.vdi

It is important hat these links are not overloaded by too many people attempting to download at the same time. It is also useful to use a fast wired ethernet connection in Auditorium C.

### Linux and Windows

On Linux and Windows machines, if the Virutal Machine does not work, you may need to enable hardware virtualization in your BIOS.

### IDL

For using IDL, you will want to make an extra modification to the VM settings, the line:

export IDL_PATH=".:+./idl:+../idl:+${PLUTO_DIR}/Tools/IDL:+${PENCIL_HOME}/idl:<IDL_DEFAULT>"

should be added to the file

/home/nbia/.profile

You will need to restart the virtual machine for this change to take effect.

If you are running out of space, you can add a shared directory to the virtual machine, which will give you a drive which lives on your host system. Roughly, the steps are:

1. Create a directory on your host system to share with the VM.
2. In the machine settings for the VM, add this directory as a shared folder, and set it "automount" and "permanent".
3. Restart the VM. Once it restarts, you should have new directory in /media which is your shared directory.
4. To make it so your user in the VM can use the new shared directory do:
sudo usermod -aG vboxsf nbia
and restart the VM.

# Superanders

1. To set environment variables to point to copies of the source codes, source the script:
 . ~cmcnally/setup_environment.sh
2. Copy the directory $PLUTO_DIR/Test_Problems to your home directory:  cp -r$PLUTO_DIR/Test_Problems ~/
